ReHo值的提取问题

您好,老师
我之前用DPARSF已经做了预处理,得到了以szReHoMap开头命名的文件,并且对两组不同的人群做了双样本t检验,找出了一些差异性脑区。我接下来的目的是想在这些有差异的脑区中,分别提取两组人群的ReHo值,方便我进一步与我其他的行为指标进行相关性分析之类的操作。
提取ReHo值这一步我实在搞不明白了,特向老师请教,希望能够得到老师的帮助。谢谢~

扫描不完整的影像图像计算问题

各位老师好,我有一批影像数据,扫描时顶叶没有cover全,那么用DPABI进行流程化操作计算DC时,这部分脑区是否还是参与了DC指标的计算?如何解决这一问题呢?

Applying High-pass filtering with DPARSFA 5.0

Hi,

1) I need to High-pass filter my data. Since my TR is 1.3 (multiband sequence), I simply typed [0.01 - 0.3] in the GUI. Is it safe enough? Or maybe should I do anything else?

2) Also,  I wonder whether there is any difference between filtering the data from the GUI's preprocessing section (which is my case, please see attached image), and filtering  from the FC section.  

3) Open question, from which I do not expect bynary (do/don't do ) answers.  Just, opinions:  How about not filtering rs-fMRI data?

请问DC指标可以用于任务态数据的分析吗?

请问一下各位老师,DC(度中心性)这一指标可以用于Task-related fMRI数据的分析吗?预处理的时候有什么特别需要注意的地方?

statistical analysis

Hi,

In the training course of statistical analysis, we are told to apply tfce+PT.

But can I use the tfce+FDR instead? 

I wonder which one is better, tfce+PT or tfce+FDR?

Thanks,

paired t-test

Dear all,

I uniformly parcellate the GM binary mask of size 61*73*61 into 6k parcels. Each parcel is a 2*2*2 cube.

So my feature is built on parcel-level for each subject.

Can I apply the paired t-test statistical pipeline in the DPABI software?

Or do I need to get back to voxel-level feature in order to use this pipeline?

Thanks!
